An Improvised Explosive Device (IED) defense system is described that forces premature detonation of IEDs by radiated sound energy signals. Embodiments of the invention provide for radiating sound energy signals from a stationary or mobile platform to a stationary or mobile area defining an "IED detonation zone." IEDs within the IED detonation zone that are triggered by sound energy sources will receive the radiated sound energy signals, thereby forcing premature detonation of IEDs in the detonation zone.
